Yes, BRCA1 is a tumor suppressor gene.
Yes, BRCA1 is considered a tumor suppressor gene, not an oncogene.
Tumor suppressor genes help regulate cell growth and prevent the development of cancer by controlling cell division and repairing damaged DNA.
APC is classified as a tumor suppressor gene. Tumor suppressor genes prevent the uncontrolled growth of cells that may result in cancerous tumors. The protein made by the APC gene plays a critical role in several cellular processes that determine whether a cell may develop into a tumor.
The two genes considered responsible for the cause of cancer are the oncogene and the tumor suppressor gene.
Oncogenes regulate cell division, so if it is placed near an overly active gene, it may itself become overly active, thus causing cancer. Tumor suppressors suppress tumors and will only cause cancer if it stops its activity, contrary to oncogenes.
A malignant gene is a gene that has mutated and is involved in promoting cancer growth and progression. These genes can be oncogenes, which promote cell proliferation, or tumor suppressor genes, which normally inhibit cell growth but are inactivated in cancer.
The p53 gene was identified by a team of researchers led by Dr. David Lane and Dr. Arnold Levine in 1979. The protein encoded by the p53 gene plays a critical role in suppressing tumor formation and is often referred to as the "guardian of the genome."
p53 is a gene that codes for a protein (p53) that is an important tumor suppressor. Although the number of pathways and roles of p53 continue to expand it is, perhaps, most well known for slowing cell proliferation or inducing apoptosis if DNA damage or uncontrolled growth is detected.
Tumor suppressor genes are normal genes that carry out several functions: * slow down cell division * repair mistakes made when DNA is being replicated * tell cells when to die (a process known as apoptosis or programmed cell death) A mutation in a tumor suppressor gene allows cells to grow out of control, which can lead to cancer ie the growth of a tumor. About 30 tumor suppressor genes have been identified, including p53, BRCA1, BRCA2, APC, and RB1. A good analogy for tumor suppressor genes is the brake pedal on a car - it normally keeps the cell from dividing too quickly just as a brake keeps a car from going too fast. If the brakes on a car fail, the car goes out of control; similarly, when something goes wrong with the gene, such as a mutation, cell division can get out of control.

p53 is a protein that acts as a tumor suppressor, helping to prevent the formation of cancerous tumors. It is often used as a marker for cancer because mutations in the p53 gene are commonly found in various types of cancer cells. Detection of p53 abnormalities can help with cancer diagnosis and prognosis.
